Total revenue per unit of output
Change in total revenue divided by change in total output
Total cost minus total revenue
Average revenue times quantity
According to the material, when a firm wants to sell more units, which statement is correct?
It must raise price because AR is lower than MR
It only sells more by reducing price; AR is always higher than MR
It keeps price constant because MR equals AR
It increases output without changing price since demand is perfectly elastic
Which statement distinguishes the three profit types correctly?
Normal profit is excess of cost; subnormal profit equals total revenue; supernormal profit occurs when price is below average cost
Normal profit is enough to keep the firm running; subnormal profit is less than normal profit; supernormal profit is any profit in excess of normal profit
Normal profit exists only for monopolies; subnormal profit occurs when TR > TC; supernormal profit is any loss
Normal profit requires TR > TC; subnormal profit requires MR > AR; supernormal profit means price equals average cost
Which condition signals subnormal profit for a firm, based on the vocabulary provided?
P > AC
MR > AR
P < AC (price less than average cost)
TR = TC
Supernormal profit, as described, is most likely observed when:
Total revenue equals total cost and the market is perfectly competitive
Price is less than average cost for a prolonged period
Total revenue exceeds total costs (TR > TC), typically in the short term and only for monopolies
Average revenue equals marginal revenue at all outputs

Under perfect competition, which characteristic specifies the role of individual firms regarding market price?
Firms set prices through collusion
Firms influence price via advertising
Firms are price takers with no influence on market price
Firms can price discriminate to increase revenue

Demand is greater than marginal revenue and less than average revenue
Demand equals average revenue and equals marginal revenue
Demand equals total revenue but not marginal revenue
Demand equals marginal cost
What happens to abnormal (supernormal) profit in the short run under perfect competition, and why?
It persists because firms can collude to restrict supply
It disappears as entry increases supply, lowering price until profits return to normal
It increases because advertising raises demand indefinitely
It remains constant because marginal revenue is fixed
What is the shutdown price in the short run for a perfectly competitive firm as stated?
P = AR = ATC
P < MR
P = AR = AVC
P = MC
Which statement best defines a contestable market?
A market where existing firms face high barriers that prevent new entry
Any market structure where potential entrants are free and able to enter, creating a credible threat to incumbents

Numerous buyers and sellers, few barriers to entry, differentiated products, and some influence on price
Single seller, unique product, and complete control over price
Many buyers and sellers, perfect information, and zero product differentiation
Why is marginal revenue below the demand curve in monopolistic competition?
Because firms face perfectly elastic demand at the market price
Because prices are set equal to marginal cost at all output levels
Because lowering price to sell additional units reduces revenue on previous units when products are differentiated
Because government regulation caps revenue regardless of price changes
Short-run outcomes in monopolistic competition can include abnormal profit when firms produce where MC = MR. What is a likely market response described in the text?
Increased barriers to entry prevent any new firms from entering
Incentives for new firms to enter due to low barriers, intensifying competition and shifting prices toward where demand meets ATC and MC
A legal requirement that firms collude to maintain abnormal profits
Immediate exit of all incumbents due to losses
In the long run under monopolistic competition, what outcome is expected as competition increases?
Firms produce at minimum ATC, eliminating excess capacity

All firms independently set prices without reacting to rivals.
Government sets a regulated price that all firms must charge.
A cartel fixes prices and output across all member firms.
According to the kinked demand curve explanation, why do oligopoly firms face limited price competition?
Demand is more elastic for price cuts than for price rises, creating a kink and discouraging unilateral price changes.
Marginal cost is perfectly constant across all output levels.
Consumers are completely indifferent to price changes in oligopolies.
Firms cannot change prices due to legal restrictions.
In the kinked demand curve diagram, what happens if a firm raises price above the prevailing equilibrium price p?
Quantity demanded falls and marginal revenue decreases as consumers switch to rivals.
Quantity demanded increases and marginal revenue rises because demand is inelastic.
Quantity demanded stays constant but marginal cost increases.
Both quantity and marginal revenue increase due to price leadership.
Why is demand described as price elastic for a price rise under the kinked demand curve?
The percentage fall in demand is greater than the percentage rise in price.
The percentage rise in demand matches the percentage rise in price.
Demand does not change when price rises.
Price rises lead to a smaller percentage fall in demand than the price increase.
When a firm cuts price below p in the kinked demand framework, what is the short-term effect if rivals initially keep their prices?
A big increase in demand and a rise in revenue for the firm.
No change in demand and a fall in revenue.
A slight decrease in quantity demanded and a rise in marginal cost.
A decrease in marginal revenue with no change in market share.
In a price war where rivals match a firm’s price cut, how is demand for the firm characterized and what happens to revenue if price falls?
Demand is price inelastic; revenue falls.
Demand is price elastic; revenue rises.
Demand is perfectly elastic; revenue stays constant.
Demand is unit elastic; revenue remains unchanged.

A sets 1andearns 3m while B sets 0.90andearns 4m.
Which statement correctly defines a dominant strategy in this context?
An option that yields the best outcome for a player regardless of the opponent’s choice.
A strategy that only works if rivals collude.
An option that maximizes joint profits for both players.
A strategy that changes based on marginal cost fluctuations.
Why can price rigidity associated with Nash equilibrium push firms toward collusion in oligopolies?
Because non-price competition is optimal, leading firms to seek legal price-fixing.
Because stable prices may leave firms dissatisfied with payoffs, incentivizing tacit collusion or cheating.
Because Nash equilibrium always results in maximum joint profits.
Because collusion eliminates the principal-agent problem entirely.
